RAILWAY-TIE PLATE AND RAIL-FASTENING.

Specification of Letters Patent.

Patented Apr. 2, 1918.

Application filed April 2, 1917. Serial No. 159,089.

To all whom it may concern:

Be it known that I, EMERY M. MGVICKER, a citizen of the United States, and resident of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Railway-Tie Plates and Rail-Fastenings, of which the following is a specification, reference being had to the accompanying drawing, forming a part thereof.

My invention relates to an improvement in railway rail fastenings and the tie plates in combination with railway ties. It is not new to use a link or bolt with a slot through it to receive a wedge, and a rail clamp dropping over the link or bolt and fitting against the base flange of the rail with a rail clamp abutting against a rear shoulder or socket to hold it in position, and to use a wedge or key through the link and over the rail clamp to hold the rail clamp or fastening down to the tie plate. What I claim as new is a tie plate with rail clamps of variable sizes fitting on the different sides of the rail and in the tie plate, and interchangeable so that the transposing of the rail clamps will shift the rail laterally. The rail clamps or fastenings having depending legs of variable thicknesses in the different rail clamps and fitting into similar sockets or against the shoulders on the tie Plate with the base flange of the rail abutting against the legs of the rail clamps and being held down by the rail clamp and the rail clamps interchangeable on the different sides of the rail in the tie plate so as'to shift the rail laterally and to narrow the gage of the track. This is important and is so made for the purpose of taking up the wear on the inside of the rail and thereby narrow the gage of the track so as to maintain the standard width of gage of the track which is very desirable in the use of reinforced concrete railway ties because the tie plates when once riveted to the reinforcement cannot be changed after their manufacture, and this interchangeable fea ture of the rail clamp enables the narrowing of the gage, or bringing it back tostandar'd gage by the mere interchange of the rail clamps on the same tie plate. This feature of narrowing the gage by means of interchange of the rail clamps is also of'great importance when using the tie plates on wood or fiber ties because in use the trafiic crowds the rail out and the spikes with-the rail and widens'thegage and it becomes necessary to narrowthe' gage frequently,

thermore, the spreading of the rail is very dangerous and causes many accidents. My invention avoids the spreading of the rail and a great many serious accidents are averted, and many lives are saved and the destruction of much property is averted.

I also claim as new a tie plate having an undercut slot or groove in it and a link or bolt slipping into the groove so as to resist the upward pressure of the link or bolt and with a leg or legs on the rail fastening extending down into sockets in the tie plate and serving as shoulders fitting against the base flange of the rail and holding it in positive position.

I also claim as new the use of an insulation bent to conform to the base flange of the rail, and fitting between the rail, the rail fastening, and the tie plate in an interlocking manner, and bisected in the center so that either half may be removed and be replaced by moving only one of the rail fastenings.

This insulation serves to prevent the electric current passing from one rail to the other through the metal reinforcement, and short circuiting the electric block signal system. It also serves as a cushion on the tie under the rail, thus absorbing the shock of the rapid'moving trains, and also serving as a silencer.

I also claim as new rail fastenings and tie plates consisting of a rail clamp with legs dropping into sockets in the tie plate abutting against the rail and a link or bolt anchored in the tie plate in an undercut slot, projecting up through the rail clamp and the combination of a key or wedge fastened through the link and extending over and down on the railway spikes, holding them firmly in position against and through the tie plate and into the Wood or fiber tie.

I attain these objects by the mechanical design illustrated in the accompanying drawings, in which Figure 1 shows a top view of a wood or fiber tie my tie plate spiked thereon, a rail across the tie plate, and a link with lugs interlocking with an undercut dovetailed groove in the tie plate and a rail clamp dropping over the link and over and against the base flange of the rail, and wedges or keys driven through the link and extending over the heads of the spikes holding the tie plate to the tie.

Fig. 2 shows a sectional view of a railway rail, of oneof the links, and one of the spikes through the lines 2*2, Fig. l, and a side view of the rail clamp and spike, link, and end view of the wedge.

Fig.- 3 shows a sectional view of the tie plate and of the link and of the spikes, and a side view of the key or wedge at the line 33, Fig. 1.

Fig. 1 shows a sectional view or the tie plate and or the rail clamp and a side view of a portion of the rail through the line 41%, Fig. 1.

Fig. 5 shows a sectional view of a tie plate and of the shim and a sectional view of a portion of the rail, and a side view of the rail clainp with. the lug extending above to admit the insertion of the shiin between the rail, the tie plate, and of the link and of the wedge.

Fig. 6 shows a top view of a reinforced concrete tie with the tie plate riveted to the reinforcement in the concrete tie.

Fig. 7 shows a sectional view of the railway rail and a portion of the tie plate and of the link and of the rail clamp and insulation on one side, and a side view of the tie plate and of the link and of the rail clamp and anend view of the insulation through the line 7-7, Fig. 6.

Fig. 8 shows a-section on line 8-8 of Fig. 7, with a concrete tie in outline.

Similar numerals refer to similar parts throughout the several views.

In my drawings 1 represents the wood or fiber railway ties in Figs; 1, 2, and the steel concrete tie in Figs. 6, 7, 8, 9; 9. represents the tie plate; 3 a section of the rail across the tie plate; 3 the rail base; t the rail clamp fitting over the link and over and against the base flange of the rail; 5 the link with an opening through which the key is inserted; 6 the overhanging lug on the rail clamp; 7 the depending legs on the rail clamp; 8 the insulation; 9 the sockets in the tie plate to receive the legs; 10 the spikes holding the tie plate to the tie; 10 the rivets riveting the tie plate to the reinforcing I beam; 11 the key or wedge passing through the link and holding the rail clamp in position against the rail and also holding the spikes down onto the tie; 12 the beveled lug on the bottom or the link in Figs. 3, 8; 13 the undercut slot in the tie plate; 14 the reinforcing I beam in the concrete tie shown in Figs. 6, 8, 9; 15 the bisection of the insulation; 16 a shim inserted beneath the rail and on top of the tie plate.

In the application ofmy invention 1 first spike my tie plate 2 to the wood orfibe'r tie la s shown in Figs. 1, 2', 3 or I rivet or fasten it by other means to the reinforcement in the concrete ties as shown in Figs. 6, 7, 8, 9. I then slide the link 5 into the groove 13 and then drop the rail clamp 4 down the lugs 7 entering the sockets 9 in the tie plate, and against the rail base3 with the overhanging lug 6 on the rail clamp resting on top of the rail base 3 and I then insert the wedge or key 11 through the hole in the link and over the heads of the spikes 10 as shown in Figs. 1, 2, 3, 5 to hold the rail clamp down'and also hold the spikes 10 down in place in the tie. The wedge or key 11 in Figs. 6, 7, 8 serves the purpose only of holding the rail clainp 4 in position on the rail base 3 or on the insulation 8 around the rail base when insulation is used. I

I use a dovetailed or undercut groove 13 in the tie plate 2 for the wood or fiber tie 1 as shown in Figs. 1, 2, 3, 5 and a corresponding beveled lug 12011 the link l for holding the link in place in the tie plate because this form of construction enables me to use a thinner tie plate as shown in Figs. 1, 2, 3, 4., 5 and avoids the cutting of a socket 9 in the tie for an undercut lug as the construction shows in Figs. 6, 7 8, 9.

I use an insulation 8 formed to fit the rail 3 and rail clamp 4.- and rest on the tie plate 2 and bisected in the center under the rail so that they can be easily removed or replaced, without disturbing the rail. The insulation is formed with side lugs fitting on the outside of the rail clamps, so that it is inter looked around the rail 3 and the rail clamps 4-, and held in this interlocked position.

I use legs of different widths or sizes on the dili'erent rail clainps 4, nevertheless fitting in to sockets 9 in the tie plate 2 on the opposite sides of the rail 3. I first place the clamp 1 with the narrower or smaller legs 7 on the outside of the rail 3, and later on when. the rail becomes worn in use, I place it on the inside and I interchange the rail clamps 1 putting the wider clamp l on the outside and crowd the rail in and then put the narrow legged clamp 7 on the inside, and I thus clamp the rail firmly using the same sockets 9' in the tie plate for shifting the rail laterally and taking up the wear thus narrowing the gage of the track back to standard width. This is accomplished without moving the spikes which appear in Figs. 1, 2, 3, 5 and without attempting to shift the tie plate 2 which could not be done in my construction as shown in Figs. 6, 7, 8, 9.

In the construction of the steel concrete tie I fasten my tie plates to the reinforceinent 14k,- preferably an I beam, although any other form; may do. I then wind a spiral around the reinforcement I beam and then pour the concrete around the entire rein- {GEEK-21118115, thus entirely" incasing the reinforc'ernent, that is in the solid concrete.

When the tie is thus completed I slide the detachable rail clamps over and against the base flange of the rail, and then insert the keys through the links and I have the tie completely constructed with my tie plate and detachable rail fastenings. The shim is inserted beneath the rail 3 on top of the tie plate 2 with a raised lug 6 on the rail clamp to admit the shim 16 as shown in Fig. 5.
